6 1 1 Introduction Overview The Standard Multiport Async Solutions The term Smartio stands for smart multiport serial I/O solution. The Smartio C104 Series multiport boards offer 4 serial ports for connecting terminals, modems, printers, data acquisition equipment and any other serial devices to the PC/AT and its compatible systems. The C104P is equipped with custom-designed ASIC chip which replaces lots of conventional ICs and reduces the board to half-size. The whole family supports 16 bit architecture. Full range of I/O addresses and IRQs are available. In addition, with on-board EEPROM for storing the configuration data, the family is designed without jumper or switch. These features make each port on the board truly independent to any other port and thus compatible with most existing multiport boards. The C104P board is also available in PCI bus. Please contact MOXA dealer/distributor or MOXA Web site for more details. C104P User s Manual 1-1

7 Hardware Configuration Method JP1 Switch Jumper C104P New : set I/O address and IRQ via software Utility. Traditional Multipoort Board Traditional : set switch and and jumper manually for I/O address and IRQ. Instead of using traditional jumper or switch for IRQ and I/O address settings, hardware configuration of each port is easily set by DOS utility, Io-irq.exe, which read and write the on-board EEPROM for configuration information through the CAP (Configuration Access Port) address. The CAP address is the only channel via which the configuration utility Io-irq.exe can access the board, which is identical to the first port's base I/O address. The only jumper, JP1, is designed in case that users forget the CAP address. Normally JP1 is left open. When JP1 is short, the CAP address is forced to a fixed I/O address, 0xA700. However, to adopt quick installation (described later), it is a must to keep JP1 always short. Quick Installation To ease the hardware configuration, users who install only one C104P board under Windows NT/95/98 are recommended to adopt quick installation described in Chapter 2. Because the series is so flexible in hardware configuration that they are compatible virtually with all kinds of other manufacturer's multiport boards using or UART. 1-2 C104P User s Manual

11 Installation Guide This section gives a brief summary of how to install the C104P under each supported operating system. The installation is simple and involves the following stages: Configure C104P with io-irq.exe. Install the C104P board See Chapter Hardware Installation Install the software from the diskette Configure the driver for the board and ports See Chapter Software Installation for respective OS Connect the devices with the cable Restart the system Check the driver initialization status If the system restart successfully, you may develop your applications or execute the desired applications See Chapter Connection Cable and Cable Wiring See Chapter Software Installation See Chapter Serial Programming Tools 1-6 C104P User s Manual

12 2 2 Hardware Installation The installation of the C104P consists of hardware and software installation. The hardware installation is detailed in this chapter. The next chapter deals with the software installation for various operating systems. JP1 C104P Default Settings The C104P has the following default (factory) settings: I/O address: 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4) IRQ: 10 INT Vector: 0x1C0 CAP Jumper JP1: Open Note! If the default settings above are what you desire and good for the system without conflicts, you may simply install the board in the system and go directly to the next chapter, Software Installation. Otherwise, follow the instructions below. C104P User s Manual 2-1

13 Now you should do either the normal hardware installation (detailed in the later section, Hardware Installation with IO-IRQ Utility ) or the quick hardware installation (detailed right in the next section, Quick Hardware Installation ). The latter is provided to facilitate the hardware installation, only under the circumstances that: u u u Only one C104P board is allowed to install in a system. Windows NT and 95/98 are the only operating systems supported. I/O address 0xA700 must be free Quick Hardware Installation To fully utilize the superior feature of flexible hardware configuration design of the C104P, a quick and easy method of installation is designed for users, which absolutely free the users from hardware configuration effort, i.e., installation without running configuration program: Io-irq.exe. Simply always short the jumper JP1. The software and hardware configuration will be completed at the same time while doing the software configuration. How to Do Quick Hardware Installation Users who install only one C104P board under Windows NT/95/98 are strongly recommended to do the quick installation as follows: 1. Short the jumper JP1 on the upper-left corner of the board. 2. Plug the board in PC with the desired system installed, which is powered off in advance. 3. Process software installation, detailed in the next chapter. This is to specify the desired I/O address, IRQ and INT Vector in the software configuration panel, no matter what hardware settings are on the board. The software configuration program will automatically update the hardware settings. After this, users already complete the whole installation. 4. Shutdown System (Windows NT/95/98). 2-2 C104P User s Manual

14 Software Installation 5. DO power OFF and then ON (or Reset) the PC. (Please cold start.) 6. Restart System (Windows NT/95/98). It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration. However, remember to cold start the system every time the configuration changed. Hardware Installation with IO-IRQ Utility This section is for those who can not use quick hardware installation: u Install two or more C104P boards in a system. u Fail to install, due to the I/O address 0xA700 is not available or has conflict in the system. u Use operating systems other than Windows NT and 95/98. Before proceeding the software installation, detailed in the next chapter, Software Installation, do hardware configuration to setup the I/O address and IRQ with Io-irq.exe, detailed in the next section. Remember to keep the hardware settings in mind for the software installation. The C104P has the following default (factory) settings: I/O address : 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4) IRQ : 10 INT Vector : 0x1C0 Because the ASIC-designed C104P has no switch and no jumper for configuring manually the I/O address, IRQ, INT vector, etc. of the boards, you must run the software utility, Io-irq.exe, in the driver diskette under DOS system to change the hardware configuration. 1. Choose a PC that has DOS system inside. C104P User s Manual 2-3

15 2. Power off the PC. 3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC, one board at a time with JP1 open. + If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings. The C104P has the following default (factory) settings, I/O address: 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4) IRQ: 10 INT Vector: 0x1C0 Configuration Access Port (CAP): 0x Power on the PC and enter into DOS system. 5. Run the utility Io-irq.exe contained in the driver diskette to set up I/O address, IRQ and INT vector of the board. Please refer to the next section, IO-IRQ Utility and Hardware Configuration for more details. Or follow the on-line help to configure the C104P board. After completing the hardware configuration, the board is ready for use under operating systems, such as Windows NT and 95/98, DOS, Windows 3.x, etc. IO-IRQ Utility and Hardware Configuration Note that the CAP address, e.g. 0x180, is identical to the first port's I/O address except in one case that the JP1 jumper is installed before powering on the PC. In this case, the CAP address will be forced to 0xA700. The CAP address must be typed correctly. With the correct CAP address, the utility can find the configuration stored in the on-board EEPROM and display it on the configuration panel. The CAP address is the only channel via which the configuration utility Io-irq.exe can access the board. 2-4 C104P User s Manual

16 Software Installation 1. Run the utility Io-irq.exe contained in the driver diskette to set up I/O address, IRQ and INT vector of the board. 2. Select Smartio/Industio ISA Family and press ENTER key. C104P User s Manual 2-5

17 3. Enter the CAP address of the C104P board to be configured. 4. Configure the following parameters as necessary. Port Index I/O address IRQ Speed Indicate the port index for each port. Enter the base I/O address for each port, either sequentially or not. Avoid to conflicting with any other devices. Enter the IRQ, 2, 3, 4, 5, 7, 10, 11, 12 or 15, for each port, independently or not. This field specifies the use of normal or high speed capability. Normal speed ranges from 50 bps to Kbps. High speed ranges from 50 bps to Kbps. C104P support only normal speed spectrum. In other word, it is not available for speed faster than 115.2K bps. 2-6 C104P User s Manual

18 Software Installation INT Vector Enter the interrupt vector I/O address for all ports. I/O address for interrupt vector is from 00000H to 0FFFFH. Interrupt vector is one byte of I/O address, in which each bit is used to indicate the occurrence of interrupt for corresponding port. To use interrupt vector, type in the hardware Interrupt vector I/O address. If not using interrupt vector, type 0 or leave blank as the interrupt vector. There are two modes for the C104P driver. One is using interrupt vector, the other is not using interrupt vector. Driver employing interrupt vector scheme is supposed to have better performance than employing polling scheme. 5.

62 6 6 Troubleshooting Common C104P problems and possible solutions are listed below. If you still have problems, contact your dealer or Moxa for help. Or use the Problem Report Form at the end of this manual to report problems to your dealer at once for faster technical support. General Troubleshooting 1. The MOXA driver, while installing the driver, cannot detect the MOXA board. Hardware causes and solutions: a. The board is not installed or missing (absent). Please install it. b. The board is not properly plugged in the system. If that is the case, re-install the board and make sure that it fits well in a 16-bit slot this time. Sometimes the slot for plugging the board is bad. In this case, try other slots until you find a good one. 2. The MOXA board and driver are activated but cannot transfer (transmit/receive) data. Hardware Causes and Solutions: a. Check for wrong cable wiring. Refer to the Connection Cable and Cable Wiring chapter for precise pin outs of the connector type you are using. b. The cable or the board is defective. You may use other ports, cables or boards to verify. In addition, the PComm Diagnostic utility for Windows NT and Windows 95/98 is good for testing MOXA boards and port conditions. If Diagnostic reports error, replace the faulty components. C104P User s Manual 6-1

63 Software Causes and Solutions: a. C104P checks the line status (CTS) before it sends data out if the RTS/CTS flow control feature is set to Enable in the configuration or application program. Please refer to the Connection Cable and Cable Wiring chapter for proper wiring. Check the line status of the suspected port using the diagnostic LED indicators on the mini tester. b. Perhaps the application controlling the board is not correctly written according to the corresponding API of the operating system. To verify, please run an existing and known good application or the provided utilities by Moxa. For example, under Windows NT and Windows 95/98, Pcomm Terminal emulator or HyperTerminal utilities are good for testing the COM ports. 3. Why the DOS utility IQ-IRQ can not access C104P to configure? There are several reasons that may lead to this trouble: a. The user forgets or does not know the Configuration Access Port (CAP) of the board. See next problem 4 for how to solve this problem. b. The CAP of the board conflicts with other add-on boards I/O address. Please change other add-on boards I/O address to avoid the conflict. c. The C104P board is not plugged in a right or good slot. Please plug the board in a good 16-bit ISA slot. d. The C104P board may malfunction. Please return for repair. If any existing board has the same I/O address as 0x180, the default CAP address, or the 1st port's I/O address, you must try to avoid the conflict by doing either one the following. a. Install a jumper (short) at position JP1 on the upper-left corner of the board. This will force the CAP address to 0xA700. b. Change or disable the existing board's I/O address. 4. What to do if user forgets or does not know the Configuration Access Port (CAP) address of C104P? The C104P multiport board is designed without jumper or switch, so the configuration is completed only by DOS utility Io-irq.exe. To configure the board, you need to know the board s Configuration Access Port (CAP) address. Because the CAP address is the only channel, via which the Io- 6-2 C104P User s Manual
